Anyone got official numbers on the S15 comp ratio because i've gotten too many different numbers and I really don't know which is right and which isn't

Yeah I'm speaking about the SR20DET, I read on a local shop that it was 10.0:1 and another online site that sold engines reported it to be the same :mad:

the 10.0 is the naturally aspirated S15 SR20DE...so just a typo
